Abstract

The invention provides an equipment isolation real-time online monitoring system. The system is used for ensuring that nodes required to be closed at to-be-overhauled equipment are in a closed state.The system comprises a central control system, a portable mobile terminal, displacement sensors and a signal relay, wherein the portable mobile terminal is carried by a maintainer and is used for inputting application information for maintenance of the to-be-overhauled equipment and sending the application information to the central control system; the displacement sensors are distributed on all the nodes required to be closed and are used for detecting whether all the nodes are closed or not; and the signal relay is used for transmitting the information between the central control system andthe mobile terminal and between each displacement sensor and the central control system. The invention further provides an equipment isolation real-time online monitoring method. Through the monitoring system and method, whether the nodes are in the closed state or not in the overhaul operation process can be monitored remotely in real time, and convenience is brought to safety management of the overhaul operation. Meanwhile, paperless operation is benefited, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production safety, in particular to the field of equipment auxiliary maintenance and overhaul operations. Background technique [0002] In some factories and enterprises, especially chemical enterprises, in order to ensure the safety of maintenance, commissioning and engineering operations, the LOTO (lock out, tag out) management system is generally adopted. For the sake of safety, chemical enterprises will require the method of isolating, locking and putting up warning signs for equipment during maintenance, debugging and engineering operations in confined spaces. In the existing method, when the chemical plant is working in a confined space, the pipelines connected to the confined space that may endanger the safe operation should be isolated by inserting blind plates or closing valves, and locked when the safety requirements are high. listing. [0003] However, in the actual operating process, the loc...
